Most vehicle suspensions systems use fixed passive components that offer a compromise in performance between sprung mass isolation, suspension travel and tire-road contact force. Recently, systems with discretely adjustable dampers and air springs been added to production vehicles. Active and semi-active damping concepts for vehicle suspensions have also been studied theoretically and with physical prototypes. This paper examines the optimal performance comparisons of variable components suspensions, including active damping and full-state feedback, for 'quarter-car' heave models. Two and three dimensional optimizations are computed using performance indicators to find the component parameters (control gains) that provide 'optimal' performance for statistically described roadway inputs. The effects of performance weighting and feedback configuration are examined. Active damping is shown to be mainly important for vehicle isolation. A passive vehicle suspension can control suspension travel and tire contact force nearly as well as a full state feedback control strategy.
